Only five listings show up here, that is because there are two lights on Michigan Island, adjacent to one another.
There are other lighthouses in the area, but they are not a part of the Apostle Islands National Lakeshore, therefore, they are not part of this listing.
The Apostle Islands are an archipelago of 22 islands, just off the coast of Bayfield Peninsula in Lake Superior. All but 4 of the islands are considered a part of Ashland County, the four westernmost islands are a part of Bayfield County. Madeline Island is the largest of the group but is commercially developed, including 247 year round residents, so it is not a part of the National Lakeshore.
The Apostle Islands National Lakeshore is a vacation paradise.
There are over 800 known species of plants on the islands, and the NPS says that Stockton Island is home to the largest concentration of black bears in the country. The bears are great swimmers and are often found on any of the islands.
The islands have a large concentration of sea caves, impressions carved out by Lake Superior over the millenia. Devils Island has the most striking collection of sea caves, that produce strange sounds when high waves crash into them. The eerie sounds are the namesake of the island.
Lake Superior has sculpted sea caves into the islands, the most striking are on Devils Island.
As part of the National Park system, the islands and lighthouses are available to visitors. During the tourist season, some (but not all) of the lighthouses are manned with volunteers who will give tours. Lighthouses may be open during Bayfield's Lighthouse Festival in September, when boat tours are offered.
